Find ground jobber drill bits and metric tap sets for drilling and threading work during door installation and maintenance. Compare the individual drill diameters and M5, M6, M8, M10 and M12 tap-set options shown in the range.

Select the drill and tap for the material, thread size and fixing specification. A tap's nominal thread size is not its tapping-drill diameter; use the appropriate drill size and the tool manufacturer's guidance for the thread being formed.
